Which CODE?

[Tevens]

For a proposed vessel of 30m, which is going to be designed wich lloyds SSC which yacht code(which will include stablity criteria) will be best applicable?

[Tevens]

the vessel will be operating far far offshore

[gonzo]

CE category A

[Tevens]

is there a link to that specifically? all i have found is the :
A: OCEAN -- Designed for extended voyages where condition may exceed wind
force 8 (Beaufort scale) and wave height of 4 m (13.0 ft) .
Is this part of the recreational craft?
The vessel in question is not for recreational usage. do you have a link to the stability criteria of that code?

[Farley]

I have been having pretty similar problem. I don't know which code to use in conjunction with the SSC. I need to find suitable stability criteria for my vessel to have to pass, does any one know where i can find the yacht codes or know which would be the best code to use? the vessel is going to be a private vessel not for rereational use and will require unlimited travel area.

Depends where the vessel is being flagged and what waters she'll by sailing in. Makes a difference...

[gonzo]

You posted "Yacht" which in the UK would be a recreational vessel. What is the intended use?

[Tevens]

research / expedition vessel

LR rules on Yacths

Pt 3, Ch 1.1.1 The rules apply to sea going motor, sailing and auxillary craft of normal form, proportions and speed, generally not exceeding a scantling length of 150 meters.
And
Pt 4 Ch 1.1.8 Yachts over 24 meters overall length, LOA maybe the subject of National or International regulations concerning constructions, safety and manning and compliance with these regulations is the responsibility of the Owners and the Builders.------

There has been a discussion on the applicable rule here on BD forum titled "Which Rule?" sometime in July. I beleive the LR rule can be downloaded from this forum or a link is provided.

However, Research/Expedition vessel is not a yacht or a pleasure craft.

[RAraujo]

For a Research/Expedition vessel you should use MSC.266(84) Code on Special Purpose Ships (conditioned to the acceptance of the flag state).

Note the applicability of the LR SSC Rules:

QUOTE
■ Section 2
Scope of the Rules
2.1 Applicable craft types

2.1.1 The Rules are applicable to the following craft types constructed from steel, aluminium alloy, composite materials or combinations of these materials:
(a) High speed craft.
(b) Light displacement craft.
(c) Multi-hull craft.
(d) Yachts of overall length, LOA, 24 m or greater.
(e) Craft with draught to depth ratio less than or equal to 0,55.

2.1.2 The following craft types will be considered upon request on the basis of the Rules:
(a) Amphibious air cushion vehicles.
(b) Rigid inflatable boats.
(c) Hydrofoil craft.
(d) Foil assisted craft.
(e) Craft as defined 2.1.1(a) to (e) constructed from wood or wood/composite combinations.
(f) Other craft constructed from composite materials.
(g) Craft with a Rule length, LR, less than 24 m and draught to depth ratio greater than 0,55.

RAraujo,

Which set of rules does Tevens have to use? LR has two sets of rules. One for Special Service (SSC) and one for Ships. Or both has to be referenced?

[RAraujo]

The only things we know is that it is a 30m deep sea research/expedition vessel. This is not enough to decide the applicable Rules.

If Tevens could give some more information (e.g. hull material, speed)...

And there are more Rules which can be applied (unless there is a specific requirement for LR).

Is the vessel supposed to be classed? If so a discussion with the Classification Society would be beneficial (and it can be done generally free of charge).

Is it a research vessel or a yacht? If it is a research vessel I'm afraid it will have to comply with SOLAS (although there will be many not applicable items as the boat is under 500GT), if it is a Commercial Yacht, then I would recommend to comply with the MCA LY2 code. Although you didn't specify the Flag, the code is recognized by most of them.
I strongly advise to try going for a Short Range vessel, as it is allowed by the LY2, because you won't have to comply with damage stability. I am doubtful that you will be able to subdivide a 30m yacht so that it passes those criterias. Also, surely the range of this boat is not enough to allow ocean-going expeditions!
CE rules are not applicable to vessels >24m.
Besides, I wouldn't choose LR SSC for such a small vessel, as it may imply too many constraints and lead to a heavier boat, if compared to other Class rules like ABS.

How long is the boat? Assuming it is more than 24m... there are no statutory stability requirements for a private vessel!! However, LR SSC has its own requirements, you will have to comply with them.

[Tevens]

the vessel is going to have a very large range, cruise speed of 12knots, max of 20. made out of aluminium.
