The Bangladesh Navy is having a new class of Offshore Patrol Vessels designed. Like the Bangladesh Coast Guard, the new platform will be equipped with a helicopter deck.

Meanwhile the Bangladesh Navy has sent a request to UKs Defence Equipment Sales Agency (DESA) for four River-class offshore patrol vessels. Two of which (Tyne P281 and Severn P282) are available for transfer since they were decommissioned back in 2017/2018.

The BN is dissatisfied with the Padma class coastal patrol craft. Its main gun has not been fired since the past over 18 months. The front structure had to be reinforced to improve stability. Now its performing as intended however the BN will discontinue building more Padma class CPCs and focus on building their offshore patrol capacity.

Pakistan and Philippines also applied for the River class OPV if we don't get all four then at least we will get two of them.

The Bangladesh Navy is having a new class of Offshore Patrol Vessels designed. Like the Bangladesh Coast Guard, the new platform will be equipped with a helicopter deck.

I thought that the Navy had a three category patrol plan. Build Offshore, Midshore and Inshore (CPC) patrol vessels with the offshore ones being the largest, longest duration patrol vessels to patrol the farthest out areas for Bangladesh EEZ zone. Offshore patrol vessels would naturally need helipads because of their long patrol duration as well as their tackling of needs for larger rogue vessels (heli patrol). This planned purchase of refurbished River class OPV's seems to be a stopgap plan. Just like the Island and Castle classes five and ten years prior.

What would happen to the five 1280 tonnes Island class OPV's and two 1430 tonnes Castle class OPV's bought earlier ? The five Island class at least are still useful and can be turned into deep sea training vessels like the sixth Island class training OPV BNS Ruhul Ameen.

We can buy two and then modify/build the rest in quick fashion. The Thai Navy modified the River class design and built two as well. Cost marginally a bit more but this is valuable experience for our yards and we get to specify (add/leave out features) to our unique naval patrol mission requirements.

This is a standard River class OPV (1700 tonnes - batch 1)

This is HTMS Krabi - modified (lengthened) River class design at 2000 tonnes displacement, one of two OPV's built in Thailand with 'BAE surface ships' design and consultancy. Notice the large 20m Helipad.

The BN is dissatisfied with the Padma class coastal patrol craft. Its main gun has not been fired since the past over 18 months. The front structure had to be reinforced to improve stability. Now its performing as intended however the BN will discontinue building more Padma class CPCs and focus on building their offshore patrol capacity.

I believe they made a mistake building the first five CPC's in the design they followed which may not have been mature as far as sea-keeping. They should have retained Damen or other consultants to finalize the design and error-check static/dynamic balancing issues and other critical factors. These factors are still important for smaller craft of about 350 tonnes displacement. They can be turned into point defense craft at the five different ports or riverine patrol or even escort/pilot vessels.Oh well - live and learn.

The 410 tonnes Meghna class CPC built much earlier to a Vosper design was reportedly a more stable craft but armed with a 40mm Bofors gun and a couple of 7.62mm MG's I believe.

Read the Damen story here for their readymade cookie-cutter approach to CPC's here.

We can still retain BAE or Damen for standard new Offshore or CPC designs (such as Damen Patrol 4207 for CPC) and fabricate/commission these CPC's locally within one year from readily available kits. Cost - about $25-30 Million a copy for CPC's on average. There are about twenty five larger navies worldwide who have done this already for CPC's.

What would happen to the five 1280 tonnes Island class OPV's

DTB says BN will replace these with River class.

BN is building up its force level.... the OPV force has more room for expansion..... a dozen to fifteen may be required by BN.... while another dozen or so for the BCG.... the role of OPVs will expand in the coming days, as Bangladesh adopts a more assertive foreign policy.... more ocean deployments will require more OPVs....

and of course, more helicopter-capable ships would be required.... there are too few of these....

CPCs are being defined in different ways - FPBs, IPVs etc..... basic purpose isn't too different......

India aims to help Bangladesh design warships
Rahul Bedi, New Delhi - IHS Jane's Defence Weekly
26 July 2018
Indian state-owned naval shipyard Garden Reach Shipbuilders & Engineers (GRSE) has signed a memorandum of understanding (MOU) to assist Bangladesh’s Khulna Shipyard Limited (KSY) in designing and building warships, Indian Minister of State for Defence Subhash Bhamre told parliament on 25 July.

The minister said that the state-owned KSY had “expressed keenness to develop skills and know-how for design and construction of ships”.

A senior GRSE executive told Jane’s on 26 July that the MOU, which was signed on 8 May, followed several rounds of “detailed discussions” between representatives from the two shipyards accompanied by senior government, defence, and naval officials from both countries.

I am sorry but this bit of news seems to be a bit on the hokey side.

There are companies in Bangladesh who are helping Kolkata yards like GRSE in modern shipbuilding practices because of invites from the Indian Govt. This was in the news less than a month ago.

GRSE is ancient - set up by the British in the 1930's. The design capability of the yard is also ancient. There has been recent BMRE, but it is older compared to KSY which was set up by the West Germans in the late 60's.

Said MOU will only help in Indian 'consultants' (i.e. RAW agents) keep tabs on shipbuilding activity at KSY Khulna. The stated reason to 'assist' Bangladesh’s Khulna Shipyard Limited (KSY) in designing and building warships is pure hokum if you ask me.

Why do we need GRSE's antiquated help in building warships when there are consultants from the UK and Netherlands like Damen and Kelvin Hughes? What can GRSE offer us? It is simply only the cheapest (least labor cost) location in India to build hulls at twice the scheduled time and well below the intended quality. Project managers' guaranteed nightmare. I am surprised the place hasn't gotten shutdown yet. Even Kochi and definitely Mumbai can boast far better builds because of better management and work ethics.

Now if there is actual plan to build Indian hulls in Bangladesh then we are talking some sense. I can guarantee 'anything' built at KSY has better weld and component standards than GRSE. I have seen what comes out of each place, though GRSE for now builds somewhat larger naval builds.

actually it depends on who requires help.....

WMS to build ship for India Inland Waterways Authority
Western Marine Shipyard Limited (WMS) on Wednesday signed memorandum of understanding (MoU) with Shalimar Works Limited (SWL), Kolkata to build ships for Inland Waterways Authority of India (IWAI).
Under the MoU, WMS will build 60 inland ships as a part of a major programme undertaken by the West Bengal Government of India to restore and activate National Waterways-01 of India.
To achieve this SWL will be working jointly with WMS at 26 is to 74 per cent partnership while WMS will provide technical expertise and know-how to SWL, which will provide infrastructure support.

Interesting. I thought we had this in place already. maybe it’s for additional capacity to complement the pipeline of new naval assets due to join the fleet.

Do you know which version of C802 we have and it’s range as it varies from 120-250km.

C-704 with 35km range too me seems kind of a waste of time personally. This is suitable only for our riverine forces as best.
