Demands on production

Brackets and openings

Classification standards

Drawings

Strength of the structureCalculated in Conceptual Design

Are the results reliable

Is there a proper way to do calculations for wooden ships? What about catamarans? If new methods are found: compare to previous

results

Find people who know more about the subject

Compatibility with GAWill only concern the machinery in the hull

Room for everything without making areas too heavy, e.g. at batteries?

Is there room for enough watertight bulkheads? If not, can the machinery be moved?Will this affect the strength considerably?

Demands on productionConsidered in Shipyard engineering

The machinery will be bought from a subcontractorMost work on the wooden frameConnecting all the machineryWiring the batteries

What needs to be checked during production?Good joints?Avoid bending of the wood?Etc.

Brackets and openingsSimple construction

No water, heating or A/C in the hullHydrogen pipes, cooling system and wiring

Where should the openings be for an effective design?

Access hatches from the passenger area

How will large cable bundles (especially from the batteries) affect e.g. watertight bulkheads?

Classification standardsAre there classification standards for wooden

catamaran ferries? If not, what standards can be used?

Standards for wooden ships

Standards for catamarans

This area will probably be unclear, at this point we need to make our own decisions on what actually fulfills all standards

DrawingsFrom CAD course

CAD model of the ship, but with assumed steel structure

Can’t be used here

Enough time to make a new model with our wooden structure?Probably not

The simple design means that new, separate drawings might be the easiest solution

Work plan and problemsStrength calculations most important

Find proper standards, if available

GA compatibility, production, openings, etc. should be quick

Solution for the needed drawings

Work plan:One person concentrates on the strength

calculationsThe other takes care of the rest

Final work plan and expectations

Ran Strength calculation (check old ones, make new if needed), drawings A lot of calculations

Tomas GA compatibility, production, openings, standards, drawings Lots of writing, searching for sources

(Initial plan, we will help each other at the end anyway)

The strength calculations can be a problem, especially knowing if results are correct. The rest should mostly be checking previous work

Personal deadlines: 17.10 Gives time for compiling and checking problems
