This notice reminds ship masters and navigators of the importance of adhering to thorough passage plans and using accurate, large-scale charts when navigating, especially near coastlines. It was prompted by recent groundings caused by poor navigation and outlines the need for comprehensive planning, monitoring positions, and not deviating from plans without reason. Masters are responsible for safe navigation even with a pilot aboard, and all crew should be properly trained in their duties.

DESIGN OF A MODEL HAULAGE TECHNIQUE FOR WATER FLOODING CAISSON ASSEMBLY.Emeka Ngwobia
Presented in this study is the engineering solution to the movement of a 63m, 45tons Caisson from a fabrication yard to a field location in the Gulf of guinea. This was achieved by dividing the whole process into three stages; firstly by using excel sheets with relevant design formulas to design the spreader bar configuration to lift the caisson from the quayside to a crane barge conveniently, showing the necessary lifting sequence employed to complete this process, also designing the lifting accessories needed which includes pad eyes, shackles, wire rope and spreader bars according to relevant codes and standards The first spreader Is an I beam of length of 25m and section with dimension 533mm by 229mm weighing 129kg/m, the second beam and the third beam are designed similarly as an I beam of length 9m and section 533mm by 229mm weighing 129kg/m. The choice of pad eye to be welded on the spreader beam was based on the working limit of the pad eye, which was analytically designed using spread sheet, performing necessary checks to make sure it will not break off during the lifting operations. It is reinforced with cheek plates at the pin hole to reduce the stresses at the pin hole. The total pad eye used for this operation is 16. The choice of shackle attached to each of the pad eye was based on the total self weight of all the lifting materials(55tons), according to the Crosby group catalogue it is an S2130 bow shackle of Nominal size 50.8mm, Stock no 1019659 and weight 23.7002kg, also the wire rope configuration chosen to based on the safe working load limit according to the Bethlehem wire rope general purpose catalogue ASME B30.5- 1995 the wire rope has nominal strength of 53.1tons, sling class 19x7 IWRC(Purple or extra improved ploy (EIP Steel).
. Secondly, by providing solutions to sea fastening for the caisson on the deck of the crane barge, which was modeled using STAADPRO, which involved support designs and loss of support designs, so as to accommodate for the hydrodynamic effect while the caisson is being transported by the crane barge, having in mind that the crane barge chosen will adequately accommodate the caisson because of the deck space required to fit the 63m long caisson, from the analysis the Caisson is supported by steel beams spaced at 10 m interval which is fastened with the aid of a clamp as seen in the detailed drawings, this caisson and beam supports are modeled with staadpro software and support reactions obtained. These supports are now spaced at 20 m intervals and analyzed to simulate a situation where there is a loss of support reaction during transportation of the caisson. A saddle clamp is to joined to a H beam for support to hold it to the deck at varying length and at the starting point a pivot made from a pad eye joined with a pin to connect the saddle clamp to allow for easy lifting of the caisson when it is at 25m to the FPSO.
Analysis and Design of Marine Berthing StructureIJERA Editor
In the present dissertation a berthing structure was analyzed and designed using different load conditions and the best possible way to construct a new berthing structure was described. All the suitable and useful data was adopted from the proposed site location at Visakhapatnam Port and studied carefully before designing the structure. The proposed berthing structure was modeled with suitable geometry using STAADPRO, after which all considerable loads on the structure were induced and analyzed carefully. Different sectional dimensions were trialed during the analysis and the most acceptable structure was designed with providing all structural members with suitable reinforcement and satisfying all marine safety conditions.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. Good Navigation Practice
Masters and navigating officers are reminded
that sound navigational practices include:
• not overly relying on any one navigational
aid;
• in particular, not relying solely on Global
Navigation Satellite System (GNSS) for
navigation, especially when navigation can
be conducted visually and/or by radar;
• the use of soundings and transits as checks
for position fixes. PSC inspectors may look
for evidence of this practice on ships’ charts;
• fixing the ship’s position at frequent and
regular intervals, including when a pilot is on
board;
• ensuring that the ship has the latest Maritime
Safety Information (MSI) for the area by
configuring the Enhanced Group Call (EGC)
or NAVTEX (if applicable) receiver correctly;
and
• cooperating fully with any available Vessel
Traffic Service (VTS).
Owners and masters are reminded that
personnel new to a ship are to be given proper
familiarisation with their watch-keeping and
navigational duties, in accordance with
provisions 6 and 7 of the ISM Code.
