Modified the crane jib sheave and hook layout on the offshore
crane vessel ITM Mariner, the existing lifting sheaves being 6 meters apart the project
was to be reduced to 2 meters improving the cranes handling in the wind.

drawings for approval by Lloyds being involved through the entire conversion and
subsequent inclining tests .

I later returned to ITM to work within the project
management team on the design of the ITM Flexiport, for installation at Port Stanley in
the Falkland Islands following the war the previous year.
I continued with the supervision of fabrication at
Harland & Wolff in Belfast and load out onto a Heavy Lift vessel for delivery to the
South Atlantic.

Other Relevant
Experience
Originally from a
shipbuilding background, I have considerable and varied experience in Marine
& Offshore Design, and possess a disciplined approach including the
motivation to work without supervision or as a member of a project team
dedicated to the ultimate goal.
I have been very fortunate
to have been given the opportunity to gain in depth experience in a variety of
other disciplines one of which has been Civil Structural detailing.
In 1983, ITM presented a
concept to modify the crane jib & hook sheave arrangement on their crane
barge MARINER, the present layout with the sheaves 5m apart handled badly on the
wind and proposed to build a new hook yoke for a 2m wide fall.
Utilising the original
sheaves, I prepared the fabrication and installation drawings of a replacement
sheave block to be installed in the existing jib, along with a new hook yoke for
approval by Lloyds.
Although the boom was
rated at 400 t installed on the barge the maximum rating was 200 t and required
the inclusion of a load cell modified boom and final load testing.
I have of course a vast
knowledge of ship structures, but in 1987 having previously worked briefly in
structural detailing offices, and at ITM Offshore where I prepared the drawings
of the portal frame warehouses for erection on the barges of the Flexiport,
intended for Port Stanley harbour in the Falkland Islands,. I was engaged by
Clarence Erection Co. in Hartlepool to assist them with a detail draughting
project.
When I arrived with a
fellow detailer we were lead into an unused office buried in a thick coat of
dust and presented with the Design Consultants package for the erection of a six
storey Sodium Sulphate Process plant, from which to prepare the fabrication
details for the workshops.
Once the office was clean,
stationary and equipment purchased with the scope of work assessed, I ordered
the steel and sub-contracted the design of the Moment Connections, and hired a
Consulting Engineer to design the sheer connections, standardised by beam depth
to give a minimum variation in cleat angles.
With the aid of two more
detailers, we completed the columns and cross bracing, followed by the floor
beams with infill structure and equipment foundations. After the delivery of our
bolt order, 450 tonne of steel work was erected with only two paired diagonal
floor beams failing to fit first time.
We continued wall &
roof layouts for the cladding and flashing details for the process plant, before
completing the grating panel layouts for fabrication, galvanising &
installation, while liasing with the client, workshops and erection team on
site.
This was an enjoyable
project during which I gained valuable experience and confidence in personnel
& project management, continuing on through negotiations on variations to
the scope of work to the presentation of the final account.
