All Ship Types
Cargo Securing
Manual Amendments
Two existing
Resolutions were amended by the MSC to ensure compatibility with
todays practices. Under item 4.2.3 of Resolution A.581(14),
the capacity of the securing points and associated lashings used
to secure road vehicles on ro-ro ships was revised from 120 kilo-newtons
(without permanent deformation - yield strength) to 100 kilo-newtons
maximum securing load, MSL (i.e., a percentage of breaking strength
depending on the type of tied down used). Annex 13 to Resolution
A.714(17),was revised with the addition of web lashings
with a maximum securing load of 70% of the breaking strength to
Table 1, Determination of MSL from Breaking Strength.
The MSC also
agreed that the approval of the Cargo Securing Manual does not convey
any responsibility or liability regarding on board securing from
the owner/master to the approving authority.
Implementation
of the ISM Code
Based on discouraging
trends showing the slow progress of ISM certification, the MSC approved
a draft Assembly resolution which draws the attention of Governments
to consider statements of ISM compliance issued by class societies,
as a basis for verifying compliance with the ISM Code.
Further, the
draft resolution recognizes the relationship between ships that
do not comply with the Code which may be regarded as increasing
the risk for marine pollution -- and the penalties which may be
provided for in laws to prevent, reduce and control pollution by
Governments under UNCLOS.
The Netherlands
and the United States informed other Governments of the program
currently underway to issue a warning letter to those ships which
have not initiated the ISM certification process by 1 July 1997.
After the 1 July 1998 deadline, tankers, bulk carriers, passenger
ships and high speed craft found by Port State Control to not be
certified to the ISM Code will be detained. If no other deficiencies
are found the detention may be lifted, but future port entries will
be refused until compliance with the ISM Code is evident.
Helicopter
Facility Standards
Recommended
standards containing structural fire protection and fire fighting
arrangements for purpose-built helicopter landing areas fitted on
ships were approved as a MSC Circular. Included are provisions for
A-60 insulation, structural analysis of cantilevered arrangements,
main and emergency means of access, fire fighting equipment and
capabilities and refueling arrangements, if fitted.
Medium Expansion
Foam Fire Extinguishing
Based on existing
standards for low expansion foam systems (MSC/Circ.582), the MSC
approved recommended standards for the performance, testing/type
approval and survey of medium expansion (20:1 to 200:1 based on
the final vs original foam volume) foam extinguishing systems. The
first periodic test of foam concentrates properties (sedimentation,
pH value, expansion ratio, drainage time and volumetric mass) stored
on board should be carried out by laboratories after a period of
three years and then annually, thereafter.
An additional
circular containing recommended standards for medium expansion foam
systems used on board chemical tankers was approved. It calls for
MSC/Circ.582 to be applied with slight modifications to the testing
procedures for alcohol resistant foam concentrates.
Engine Room
Arrangements
A draft MSC
Circular was approved, subject to finalizing fire protection matters,
containing guidelines for engine room layout, design and arrangement
on all ships, drilling units and high speed craft. Included are
recommendations for tagging electrical
Additional
aspects to enhance the safety of man-machine interface in the engine
rooms include maximum noise pressure levels together with other
occupational health issues including ventilation/HVAC (ISO Standards
8861 and 8862, respectively) and recommendations for minimum levels
of illumination.
Ballast Water
Exchange
Certain Port
States, including Australia, Canada, several EU Member States and
the United States, require operators to undertake measures to minimize
the transfer of harmful aquatic organisms and pathogens through
the ships ballast water and associated sediments (i.e., ballast
water disinfection, heating and/or exchange) and that the treatment
chosen be documented in a ships Ballast Water Management Plan.
Of the treatment
alternatives available, the most practicable measure at present
is by carrying out ballast water exchange at sea. This involves
two proposals: (1) the flow through method which requires the continuous
exchange of ballast in order that the tanks volume is replaced
three times or (2) a single, complete ballast exchange. In either
case, the process should take place in the open sea (e.g. at water
depths > 2000 meters) in order for the concentrations of organisms
to be reduced by approximately 95%, which is considered as an acceptable
level of risk reduction.
To address
the safety aspects of those vessel currently exchanging ballast
for such an extended duration at sea, MSC68 approved a Circular
addressing the additional hazards and potential consequences associated
with this type and extent of ballast management. The circular cautions
that operators give due regard to tank pressurization, admissible
weather conditions, contingency planning and crew training to facilitate
effective monitoring and control of the ballast exchange process.
Initial Testing
of Watertight Bulkheads
The MSC agreed
to a revision of SOLAS Regulation II-1/14.3 (scheduled to become
effective 1 July 2002) by allowing an alternative to the previously
mandatory hose test. In cases where damage to machinery or electrical
equipment can occur if water were to be introduced, a visual examination
of welded connections supplemented by a dye penetrant or ultrasonic
leak test, as deemed appropriate, may be applied.
