Method
Statements
- Working with
many Marine Warranty
Surveyors from many
countries over many years,
Grand Marine has created an
effective Method Statement
"procedure manual"
incorporating the latest
Project Management,
Operational, HSE, JSA, FMEA
procedures in an easy to
reference document for your
project.
- Whether
Load-out/in, Transport, or
Float-off/on we can easily
tailor the engineering into
a specially designed Method
Statement that marine
warranty surveyors demand
today.

Bottom
Reaction Submersible Barge
-
A bottom reaction
submersible barge allows the
client to load a structure
with dimensions that exceed
the barge itself. Detailed
stability, structural, and
ballasting calculations are
used allowing the barge to be
ballasted to a predetermined
depth using the barge transom
grounded on the seabed to
allow a calculated timely
float-on or float-off in a
given marine environment.
- Pre-existing
ballastable barges are common
and can be modeled to suite a
specific requirement.
-
Barge conversions to
"temporary" semi-submersible
are commonly engineered on an
"as required" basis.
- Specifically of
benefit to the Oil & Gas
industry, Jack-up,
Semi-submersible, Jack-up ships,
Matted rigs, etc.
- Often used in the
constructing and launching of
bridge tower base, "template"
structures.

Graving
Docks
- Sectioned graving
docks can allow "stacking" of
barges and/or similar naval
structures
- Docking plans, and
damage condition docking plans
accounting for localized
stresses have been engineered.
- Often used for
"floating bridge" section
construction
