01.
Dry-docking
Ship Condition Report Categories
As part of the damage repairs the vessel will need to undergo a dry docking at which time the side valves and
underwater coatings must receive normal attention.
02.
Tank Cleaning for Dry-dock
All the spaces within the hull have been flooded with seawater. In addition, there was varying degrees of
contamination of the spaces with mud, fuel oil and lubricating oil.
All spaces in the hull and accommodation areas must be pumped dry, washed and degreased with all residues
collected and disposed of as required by the local authorities. Once the contaminants have been removed a
high pressure fresh water water wash will be essential to remove any remaining salt deposits.
The oil tanks for fuel, hydraulic and lubricating oils and the engine sumps must be emptied and the contents
disposed of in the correct manner.
03.
Hull Cleaning, Scaling and Painting
After a high pressure water wash a 300mm strip of the topside shell plating immediately below the rubbing
strake on the port and starboard sides will require blasting to restore the substrate to a suitable condition for
coating.
On the chine where the side plating meets the bottom plating in way of the lifting strops when the vessel was
recovered there is some coating and metal damage. This needs to be cleaned and blasted before the necessary
repairs, if any, can be determined and effected.
Otherwise the coatings are generally sound and will require only routine dry dock maintenance prior to a return
to service.
04.
Dry-dock Paint
After the accommodation, decks, topside and underwater hull have been high pressure water washed and any
damaged areas suitably prepared all surfaces will require to be fully coated.
05.
Hull
The hull is constructed of aluminium and is of catamaran design. The external and internal structure is in good
condition but there are a few minor damages to be addressed during the upcoming repair period prior to return
to service.
06.
Sea Valves and Chests
All sea valves are to be listed for overhaul at the upcoming damage repair period.
07.
Rudder and Steering Gear
The steering gear hydraulic system drives a ram on each rudder. The hydraulic power is normally supplied by
the port Main Engine PTO but can be cross connected to the starboard engine PTO if necessary.
The electrical systems associated with the steering systems, located in the port engine room are beyond repair
and will need to be renewed in their entirety.
The port rudder assembly has been obviously damaged when the vessel sank and it is suspected that the
starboard one will be similar. The rudder assemblies will require to be dismounted, stripped and checked and
reassembled after full alignment checks and adjustments have been carried out.
08.
4
Propellers, Shafts and Sterntubes
The port propeller shaft is seized and one of the blades nicked. The assembly carrying the rudder also carries
the stern bearing and it is suspected that the damage referred to in the Rudder text above has caused a
misalignment.
Whilst it is possible to turn the starboard propeller it is suspected that the carriage assembly has suffered and
impact when the vessel hit the bottom so this two will require disassembly and careful alignment checks before
reassembly and return to service.
09.
Anchors and Cables
The anchor looks to be in good condition and should only require routine inspection during the repair period
10.
Windlasses and Mooring Winches
The vessel has a windlass and a trolling winch both powered by the vessel hydraulic system supplied by the
PTO’s of both main engines. The winch and windlass appear but should be overhauled for bearing renewal etc.
The hydraulic systems will need to be flushed and the control systems overhauled.
11.
Masts, Cranes and Derricks for Cargo and Stores
The after lifting frame appears to be undamaged but was subjected to severe loading while the vessel was lifted
off the bottom. The structure of the unit including the foundations is to be carefully inspected and the welds die
checked prior to recommissioning. The hydraulic system will need to be flushed out and the controls reinstated.
The lifting wire has been damaged and will require replacement.
The Hiab crane on the port side of the after deck needs to be fully overhauled by a manufacturers approved
technician.
The port hauling crane on the starboard side of the after deck will require a full overhaul by a competent
technician.
On completion of repairs all the cranes must be load tested as required by the authorities.
14.
Ships Service tanks and Void Spaces
The vessel has 4 bunker storage tanks independent from the vessels structure, two in the port hull and two in
the starboard. The port tanks remain in place and no Marine Gas Oil has leaked into the hull. The forward
starboard tank however has become partly dislodged from it mountings and fuel has spilled into the space and
migrated into the starboard store forward of the tank room most probably through the bilge system.
In addition, there is an 80 litre fuel tank which supplies the gen set situated in the generator room on the main
deck level
All these tanks have been contaminated with sea water and will need to be emptied, cleaned and washed and
properly checked out before being repaired as necessary and returned to service.
The vessel has two storage spaces, one in each hull, situated forward of the “tank rooms”. The starboard space
has been contaminated by fuel from the displaced tank noted above.
Both store spaces also have suffered an ingress of sea water and mud such that they require to be pumped
out, note the fuel comment, fully degreased and high pressure fresh water washed.
The starboard store space contains the fresh water storage tank, the fresh water system pressure pump and
hot water calorifier. The tank, calorifier and system will need to be effectively cleaned out and the system hypochlorinated prior to return to service.
Forward of the Dry Deck Area in the accommodation at main deck level is a cross space which gives access to
the above noted port and starboard stores spaces located in each of the hulls. There is a minor forward shell
damage right forward of the cross space. Additionally, on the starboard side of the space the side shell plating
longitudinal stiffener one below the main deck is distorted over a length of 2 meters and will need to be repaired.
15.
5
Deck Piping
There is not a great deal of piping on deck but what there is appears to be in good condition. All systems should
be cleaned and flushed.
16.
All equipment was submerged and is beyond repair thus must be stripped out and renwed.
17.
The bridge and the galley/messroom are the only two spaces that can be considered accommodation style with
insulation and bulkhead panelling. These spaces require to be stripped out completely back to the structure of
the ship and after careful cleaning have new insulation and panelling installed.
All of the electrical cabling and equipment in these areas is beyond repair and will need to be renewed.
18.
Main Propulsion - Diesel
The vessel is fitted with two main engines, one in each hull. The details of these are:
Manufacturer: Scania
Type: D1 14 69 M 48E
Year of supply: 2002
Power: 750 HP
Serial numbers: 6503779 and 6503780
Each engine has its own Scania automation and monitoring system.
Each engine has PTO’s for a sea water pump, a hydraulic pump and an alternator.
Each engine is directly coupled to a reversing gearbox and clutch arrangement as follows:
Manufacturer: TwinDisc
Model: MGX-5114 SC
BOM #: 45650
Serial numbers: 5KU645 and 5KU646
Ratio: 2.04 to 1
Each gearbox has its own Twindisc automation and monitoring system.
The engine rooms of MMV Ostrea were totally flooded with sea water for a month. Whilst the engine rooms are
now longer flooded the engines have had no preservation work done since the incident thus will be seriously
corroded internally.
There is no space in the engine rooms thus the engine and gearbox assemblies will need to be lifted out of the
ship and taken to a manufacturers approved workshop.
There are two options:
1. Completely strip all the machines of all components, assess their condition and renew as necessary prior
to rebuild and testing. The alternator and all electrical arrangements will need to be renewed as will all
associated cabling and switches etc.
2. Purchase new engine and gearbox assemblies with all of the associated equipment for the PTO’s, electric
generation, automation and monitoring system. In other words, the complete package.
Option 2 will more than likely be the most cost effective.
20.
The vessel generates 24v from main engine driven alternators on each engine and she has a 25kw diesel
generator set which delivers 25kw, 230v, single phase, 60 Hz.
All of this equipment is unserviceable and will need to be removed from the ship and will need to be renewed
after the spaces have been properly cleaned and prepared.
21.
The main switchboard is on the bridge and with the following capability:
6
24 V DC: Supplied by the General Services Essential Batteries and the alternators of the main engines.
12 V DC: supplied from a converter, one 230v AC/12V DC and the second 24V DC/12V DC reducer.
230 V AC: Supplied by the Generator Set

These units require to be renewed.
The following 24 Volt battery banks are fitted:
Port ME Start.
Stb ME Start.
Gen Set Start.
General Use/ essential.
All the batteries must be disposed of in the correct manner and new replacements fitted
22.
Auxiliary Electric Motors and Starters
All of the vessels electric systems are beyond repair and must be replaced.
23.
Heat Exchangers
All the heat exchanges on the vessel will require to be removed, cleaned and refitted in good order.
24.
Auxiliary Machinery
There is very little in way of auxiliary machinery not already noted in other sections. There is one Fresh Water
pump a Sea Water pump both and 6 bilge pumps all of which look to be damaged and in need of replacement.
The vessel has two hydraulic systems supplied by PTO’s from each of the main engines. These systems supply
the cranes, lifting frame, winch and windlass.
There is a cooling and storage tank for each system situated aft of each engine room.
The port tank appears to have been over pressurised and this needs to be investigated. Both systems will have
to be drained, flushed and cleaned prior to assessment for repair.

25.
Domestic Services Equipment
The Galley area is for food storage and production as well a mess room for the crew. The fridge, cooker hob,
oven and vent fans are all electric and were damaged beyond repair when the vessel sank.
26.
Engine Room Piping
There are no obvious defects in the piping but it will require to be dismantled and thoroughly cleaned before
reinstatement.
27.
All of the vessels instrumentation, monitoring and control systems have been rendered unserviceable when the
vessel sank, all will require to be renewed.
28.
Engineroom General
The engine room bulkheads and deckheads are insulated with approximately 40 mm thick rock wool faced with
aluminium sheet. The insulation has been soaked in sea water contaminated by river mud, lubricating oil and
fuel oil. As such all will require to be removed and properly disposed of.
There is also a significant amount of river mud on the decks and bilge areas and this needs to be removed.
After the above the whole space should be high pressure fresh water washed.
From what could be seen the structure of the Engineroom appears to be in good condition below the mess but
once the space has been cleared and cleaned this can be confirmed.
During the repair period the insulation will need to be reinstated.
29.
Survey Status and Works
The vessel is Classed by Mecal on behalf of the flag authorities.
All repairs and new equipment must meet the standards required by Mecal.
During the repair all Class and Statutory surveys must be carried and new certificates issued.
30.
Safety and Fire Fighting Equipment
The vessel has a fixed fire detection system which serves all spaces, 16 zones. This is now beyond repair and
will need to be renewed in its entirety.
The engine rooms are protectedin case of fire by a CO2 smothering system. This system is manual release and
will require a manufacturers overhaul before a return to service.
The balance of the vessels firefighting equipment is portable and will require to be inspected by the manufacturer
and serviced or renewed as necessary.
The vessels lifesaving equipment, liferafts and life jackets, will require to be assessed by a certified company
and serviced or renewed as necessary.
47.
Main Communication and Navigation Equipment
All of the vessels communication and navigation equipment has been fatally damaged during the sinking. This
equipment and the bridge console will require to be renewed during the forthcoming repairs.
