”This resonated with New-Jersey-
based Caldwell Marine International
(CMI), a company focused, amongst
many activities, on the shallow water
aspects of windfarm cable
installation.”
CMI had considerable experience
using surface-supplied jet sleds, but
were keen to embrace the
advantages offered by a tracked
subsea vehicle, especially one that
was crane launchable and "surface-
supplied" with Its jetting pumps
installed topsides on the support
vessel – an arrangement they were
very familiar with. A keynote is its
modularity
“A key USP of the Hi-Traq Jetter
range is that there are two main
variants: the surface-supplied
amphibious Hi-Traq Jetter and the
deep-water Hi-Traq Jetter,” said
Haylock.
“Whilst being completely
independent vehicles, they are
almost identical, sharing a vast
amount of design features and
components. Whereas the
Amphibious Jetter can operate from
the beach down to around 80m, the
deep-water version includes all of
the subsea pumps, HPUs, etc, to
operate in deeper waters.
“It effectively takes over where the
amphibious vehicle leaves off and
can operate down to around 2000m
water depth.
“Between the forward and aft
levelling system of each vehicle is a
core central chassis. This chassis is
simply pinned Into place, meaning
that should a customer require both
