Boat Inspection surveyors dubai.
The following is by no means a comprehensive list of items that Constellation Marine’s inspector should visually check:
(a) The surveyors Towing Gear
Visually inspect the sections of tow wire visible on the towing winch and spare wire reel. Inspect the end thimbles, shackles, pennants, gog wires and gog system components, towing springs and other working wires, including tuggers and small gear. Carefully inspect gear lockers and tow gear stores.
(b) Ancillary Gear
Visually inspect items such as pelican hooks, grapples, chasing hooks, stoppers, hand tools, cutting gear (oxyacetylene) and look for spare bottles and length of torch hoses. Inspect welding plant, portable pumps and generators.
(c) Towing Machinery
Constellation Marine’s inspector inspects the machinery for obvious damage, signs of adequate greasing and maintenance. If the machinery is hydraulic, how much spare oil is available. If driven by auxiliary machinery (diesel engine) are there sufficient spares for repair or interchangeability of spares between engines doing other duty. Inspect band brake linings for wear down, feel for excessive ridging on bull gear teeth. Inspect emergency/manual controls for signs of regular use. Ask for towing pins, shark’s jaw etc. to be operated, also capstans, lead dollies etc. Note the methods, rigging needed to disconnect, reconnect tow wire bitter end and the rigging required to spool on spare tow wire – how long would it take?
(d) Working Deck Area
Constellation Marine’s inspector carefully examines the roller at the stern for obvious damage by anchors etc., which might cut tow wire chafing on it. Similarly, examine stem gates, chafing bars and crash bars in way of the tow wire to find any points where the tow wire might be damaged if it chafed on them.
Boat Surveyors Notes the securing arrangements of hatches on the main deck level and the condition of watertight doors and closing devices into the quarters block and engine room at main deck level. The access hatches to rig chain lockers are to be properly secured as must be the chain pipe closures.
He examines wooden/steel areas for general condition and security. Overside, notes if tyre fenders are properly secured.
At the vessel’s quarters, if fitted with portable dolly pins do the pins exist and would they fit the holes provided?

At the Bow
Constellation Marine’s inspector examines the windlass and judge its condition.
(f) Inspection of Boat Mooring Ropes
Constellation Marine’s inspector checks if the mooring ropes cared for and in reasonable condition.
(g) Machinery Spares
Constellation Marine’s inspector notes the hours run on both main and auxiliary machinery and questions the engineer on when overhauls were done. The engineer is asked to show the main and auxiliary engine spares and ascertain if sufficient are on hand – at least to class requirements.
Constellation Marine’s looks for obvious signs of machinery which are damaged or inoperative and find out why and what was being done about it. In the workshop, he looks for adequate tools and equipment. If the vessel has to use disposable filter cartridges for fuel filtration, how many may be available? Do fuel and lub oil purifiers exist?
If the main engines run on fresh water jacket cooling systems, the Constellation Marine’s inspector checks if there are adequate stocks of water and chemical treatment. If necessary, or thought desirable, he asks to have the main and auxiliary machinery powered up. He listens to it and asks for it to be operated. He examine bilges, tunnels, wells, steering flats etc for cleanliness and signs of adequate maintenance.
(h) Bridge Area
The condition of the main controls is best judged by seeing the boat operated. Obvious signs of machinery/equipment removed in bits, inoperative or missing are prompt questions concerning the reasons why.
Constellation Marine’s inspector notes the readings and gauges on winch controls, for example, tension meters on the towing winch control station, which show say 50 tonnes when nothing is connected and the machinery is not in use. This prompts a query.
He notes any obvious control layout faults which may hinder or affect the boat’s performance.
An example would be the fact that the manual engine and thruster controls are offset to one side of the aft control station, the boat normally being controlled by a PosCon Box mounted in the centre line next to the winch controls. If the PosCon becomes inoperative, then two men will be needed to operate the boat.
On modem boats, remote control TV cameras provide the master with pictures of the towing winch drums. If these fail, the winch may have to be worked blind.
(i) Other Topics
Constellation Marine’s inspector questions the master concerning the method of towline control. For example, if the anchor handling drum is used as the aft gogwire control, can the towing drum and anchor handling drum be operated simultaneously. If not, what method is used?
If towing wire protection sleeves or shoes are not fitted, what is the master’s policy regarding dealing with chafe?
He tries to find out how much work the tow wire has done, miles towed, time installed, examination, end for ending etc. Also tries to ascertain the master’s own preparations for normal emergencies such as towline breakage. For example, does he have spare sockets, bulldog grips, socketing materials for reterminating the main tow gear? He questions the master about his food and water endurance and the date of the next scheduled crew change. These factors may seriously affect performance of the boat and its crew.
(j) Other Equipment
Constellation Marine’s inspector surveyor looks at the lifeboats, life rafts, work boat and rescue boat if carried, for obvious damage. He assesses the suitability of any boats the tug carries for use at sea in rescue, transfer of personnel or equipment etc. In this respect, launching and recovery arrangements are as important as the sea-keeping ability of the craft.
He also looks also at the firefighting/emergency equipment, including rocket lines.
