Naval v Commercial Shipbuilding Rules - Think Defence
"Not a Boffin

There seems to be an awful lot of confusion here on what constitutes “Naval” and “Commercial” standards. This is also being mixed up with poor requirementeering, for which as SI rightly points out, the most important thing is to ” Know what it is you are asking for!!”.
When Ocean was contracted for (1993 – remember it well), there was basically a choice between Naval Standards (SSCP23 for constructive design, NES 154/155 for build and inspection, various other NES for machinery, outfit, magazines etc etc) and “commercial” Rules (eg Lloyds Register Rules & Regulations for Commercial Ships). For a variety of reasons, VSEL/Kvaerner went with LR for the design of the hull structure and probably the main machinery. Other items of equipment were specified against what was believed to be the “appropriate” standard. The problem being that there was very little input from MoD/the user to confirm this was the case, the classic case in point being the LCVP davits. The davits were perfectly normal davits such as you would find with lifeboats dangling off them on commercial ships. Perfectly fit for that purpose, which basically involves a proof test for MCA once a year where you demonstrate that the davit can lower the boat. Not so good for the sort of intensive use you get with Royal, where the davits are operated several times a day – in other words the duty cycle assumed for the requirement was totally inappropriate. Hence off Sierra Leone, three of the four LCVP points were unusable within hours of the op commencing." |
