On 3 January 2012, DNV granted type
approval to the Mark II model of OceanSaver,
which is a tailored version of the already type
approved Mark I model, but with the most
‘energy demanding’ features of the Mark I
model removed. The Mark II model introduces
better-performing filtration technology and
reduces piping installation, which saves both
time and money.
Previously focusing mostly on the
larger-sized vessel segment, OceanSaver
is positioning Mark II as a cost-effective
solution for the medium-range vessel market,
thus expanding its client base.
OceanSaver’s focus is not only on
procurement costs, but on Mark II’s entire
lifecycle costs, including spare parts, energy
consumption and manpower. The energy
required for the complete system and related
equipment is 50% less for Mark II compared mp
with Mark I.
OBS
OptiMarin

The Optimarin Ballast System (OBS) is based
on filtration as pre-treatment and high doses
of ultraviolet irradiation for inactivation of
marine organisms.
The OBS does not use or generate
chemicals or biocides in its treatment or
cleaning processes. Ballast water is treated
both during ballasting and deballasting to
ensure the dual UV effect. Ballast water is
filtered only during ballasting.
The system is normally installed as close as
possible to the ballast pumps. The modular
system is flexible, with a relatively small
footprint and weight, and will fit vessels of
different kinds and sizes. The OBS can be
delivered as a complete skid or as a customised
solution. It accommodates a wide range of
ballast water capacities and can handle flows
up to 3,000m3 /h (or higher upon request).
The MicroKill UV chamber has one UV
lamp, with a flow rate of 167m3 /h, which can
be installed in parallel on a single manifold for
higher flows.
The chamber is specifically developed and
manufactured for installation aboard ships.
It is self-cleaning, with no moving parts or
need for chemical cleaning. There is a UV and
temperature sensor in each chamber.
Optimarin offers two 40µm filters: BSF
MicroKill basket type and B&K MicroKill
candle type, both of which have automatic
backflushing and are self-cleaning. ning ng ng.
