Anyone Interested in Ships

An LCV at anchor. Despite the small size these are expensive and very capable vessels, designed for offshore inspection, maintenance and installation work. The crane os an over-boarding crane for sub-sea operations, they can work in depths of many hundreds of metres.

Can't remember if I posted these already, but this is what happens when ships go bad. The big ship is an OBO, loaded with gasoline, it collided (twice....) with a gas carrier. In the English Channel. How it all didn't go up in a colossal fireball was just good luck. We patched up the hole and then escorted it to Rotterdam. Several thousand tonnes of gasoline escaped. This was one of Farstad's AHTSS, we spent the summer anchor handling in the North Sea and winter as the Coastguard emergency response vessel for the Dover Strait.

Those make me think of what one does with the "left-over" parts from all of the ship models the you have built! They just look so "un-balanced".

This is a clearer pic of the Maersk AHTSS I posted a while ago, they're still at anchor. These really do look like a cut and shut, the front half is really quite rakish and has a bit of style, the rear half is a low freeboard working deck for working anchors. They really do look odd.

AHTSS and many other offshore vessels are unusual in that the main wheelhouse work area is the after bridge. On location the deck officers control the ship from the aft control station, working cargo or doing offshore installation work, doing anchors etc they need to monitor the aft deck and maintain station and heading relative to the rig, work activity etc. When I was on AHTSS (for the same company funnily enough, Maersk), when working anchors I sat next to the mate or master and drove the winches and deck machinery while they drove the ship. At that time we did six hour watches (six on/six off) and usually the master would work with the second engineer and the mate with the chief engineer. The winches on these ships are huge, very impressive, they're in the winch house below the bridge. The low freeboard is necessary for bringing anchors, bouys etc over the stern roller and onto the deck.

Since we're on offshore vessels, this is the workhorse of the sector, a platform supply vessel (PSV). These carry cargo on deck. In addition they have complex tank and silo systems below deck for drill water, potable water, fuel, mud, brine, base oil, dry bulk like cement and bentonite etc. Despite the small size they're impressive ships.

Another offshore vessel, this is a survey ship.

 

[jjb1970]

Some container ships today, around Pasir Panjang and Tanjong Pagar.

 

[jjb1970]

A big one.

 

[jjb1970]

Some tankers today, off Pasir Panjang, near the oil refinery.

 

 

[jjb1970]

This is an unusual one, a cement carrier.

 

[jjb1970]

These are the workhorses of the fleet, geared bulk carriers.

 

[jjb1970]

There doesn't seem to be much love for this old girl, been sitting at anchor for ages. During the pandemic anything that could carry containers could be fixed for $$$$$$$$$$$s but the market has really cooled off.

 

[jjb1970]

This one is a long way from home.....

A view of the LCV showing the low freeboard, similar to an AHTSS. Older examples often were AHTSS modified with an over-boarding crane and additional equipment, and some of the big AHTSS are designed to be adapted to LCV configuration but nowadays they tend to be designed and constructed as LCVs. These are a bit like the Swiss army knives of shipping, they can perform all sorts of functions, these days most dive support vessels (DSVs) are based on LCVs with decompression chambers added. They have accommodation for a lot of people as when mobilized they carry a lot of contractors, which leads to a bit of a legal anomaly. They're generally built to comply with the SPS Code, and the contractors are 'special persons', however strictly speaking the SPS Code is detached from SOLAS.

I take it  the main propulsion machinery is in the forward part?

That varies. Platform supply vessels tend to have the engines well fwd, quite often with high speed shafts to gearboxes at the aft end or diesel electric drive. AHTSS and LCVs sometimes have them a bit further aft ( midship or just fwd of midship), but they can be fwd. The AHTSS I sailed on were about half and half fwd and midship engine configuration.

The biggest ship that I have a current photo of:

This small tanker was an unusual visitor to Newhaven, East Sussex, recently. Most of the traffic there, apart from the DFDS ferries to Dieppe, is from the aggregates and scrap metal trades. The former includes both freighters and dredgers. A cross-section can be seen in my album on the other website I frequent - http://www.ipernity.com/doc/philsutters/album/1017594/@/page:12:18

Any cable ships around these days? Global Marine were regulars about 20 years ago when I was in SG.

One week tomorrow I shall start 24hour on a guardship *** for this.

 

A previous year's video.

 

 

***, 30 to 40 ft motorboat, with radio, to report boat positions, rescue dory, first aid kit etc.

In a slightly smaller league, can we celebrate Glenachulish, that uniquely daft Scottish design that could load both port and starboard? But not both at the same time. A good modelling opportunity, along with a couple of Clyde Puffers.

Thanks for posting that Keith. It really takes me back. We had several family holidays in the Western Highlands ( I think my father liked rain and midges!) and I can remember going to Skye on  the Glenelg ferry as well as another crossing and the turntable car decks on the Glenelg ferry seemed very Heath Robinsonish. This would have been in the late 1950s early 1960s so none of the ferries we used would have been the Glenachulish but I didn't even know that these small ferry boats even had names. I 'm sure we also used the Ballaculish ferry but can't remember what sort of ferry was in use on the other short crossing to Skye.

It all brings back memories of single track A Roads with passing places and staying in Highland B&Bs. We used the Motorail service at least once to get up there but also the "Starlight Special" (a cut price overnight train with day carriages only) with a hire car from I think Edinburgh.

The Ballachulish ferries were of the turntable type, as were those at Kyle. The former of course replaced by the bridge and the latter by landing craft style Ro-Ros of the type well used by Calmac on their low volume routes.

The Kyle ferries were operated by the Caledonian Steam Packet (i.e. LMS then BR) and were a solitary outpost of the CSP in what was otherwise MacBrayne's kingdom.

Most cable repair and inspection ships now seem to be LCVs mobilised for the task, cable layers may still be dedicated ships but they're a bit less common. 

 

LCVs are really very impressive ships, they can be configured for dive support, ROV ops, cable inspection and repair, well intervention, construction and just about anything else.

This is one of the oddly proportioned Samudera ships. The bow is very typical of current Japanese ship design, many of their designs have a vertical bow with no bulbous bow. Bow design is a very happening area of naval architecture, after decades where they followed a pretty standard template there has been a lot of innovation, probably most famously with the X-bow.
