A typical container deck cargo which is food, stores, spares, in fact, almost anything. The flexible pipeline across the top is pumping fresh water.

Below decks there are fuel oil, bulk cement and other chemicals which are discharged through flexible hoses by compressed air.

 

From this diagram you are able to see what these ships are like below decks.

From the left you can see the stern flat, housing the electric motors which power the main propulsion thrusters. Next are the large white tanks which carry drilling mud which is very heavy and the pumps to discharge it about 120 feet to the platform or rig.

Then there is the engine room where four diesels drive the alternators, which produce the electricity, to supply the ship and drive the propulsion thrusters. In the engine room is an air conditioned control room and workshop for all the ships machinery.

The bridge section has quite spacious accomodation for 26 people, and can take 250 evacuees or survivors from a rig. The accomodation includes all the single berth crew cabins, with a maximum of two persons sharing a bathroom, but mostly 'en suite'.

Captain and Chief Engineer, have seperate bedroom,dayroom,and bathroom. There is an office with shore linked telephones etc.

There are also the officers saloon with coffee area, and crews messroom. A large communal recreation room with VHS videos. There is a very large galley, with central island cooking facillities. There is a hospital with two beds, and full medical, and surgical equipment.

Beneath the bridge are the silos which carry the bulk cargos such as dry cement, barytes, and many other chemicals.Then at the fore end is the bow thruster rooms with store rooms and walk in fridges and deep freezers

From the area where the engine room is, you can see the ship has a double hull.  All the liquid cargos are carried here. It is possible to walk the full length of the ship below decks. It is sectioned off though, with massive watertight doors which all close automatically, in the event of problems.

"Pearl Marine" is a 100,000 tonne Oil Tanker which was converted to heavy lift crane. Italian Owners, but flag of Panama. I worked with this vessel for some time in the Argyle Field, North Sea. Consider the smaller crane is as big as you are likely to see ashore. Big one will lift about 3,000t

"Seaforth Monarch" with a mixed cargo of Fuel Oil, Bulk Cement, Fresh Water, Pipe casing which goes down the well, and  containers. Note the main towing winch beneath the accomodation and the wire spooling reels, above it. A jolly nice but rare day. Thanks, God.

Bredford Dolphin Heavy Lifts.(51661 bytes)

Not a nice day but we were still discharging cargo to another crane above us. Waves about 20 feet. When I get my slides converted to scan them I have a similar picture with a 120 foot wave !

Discharging 30 ton lifts of zinc anodes to the Atlantic I. A much more 'normal' day. Quite a lot of cargo to the Rigs and Platforms consists of 'Heavy Lifts'.
