On 12 May 2013, three of his personal staffs VK Sasidharan (additional private secretary), A Suresh (personal assistant) and K Balakrishnan (press secretary) were ousted by the Politburo, which was entrusted by the CPI(M) central committee to decide on the action to be taken against them. They were expelled on charges of leaking information to media, according to CPIM. With the decision, Achuthanandan's arch-rival and Communist Party of India-Marxist (CPI-M) state secretary Pinarayi Vijayan appears to have won. The state committee of the party where Vijayan has a huge majority also wanted Achuthanandan to be removed from the post of leader of opposition but this was not done. "This is a clipping of the wings of Achuthanandan", said K.M. Shahjahan.

In 2017 Sarvekshak became the 1st ship of Indian Navy ever to deploy solar power. It has innovatively deployed the zero-maintenance solar power system, capable of generating 5.4 kW electricity and replacing the ship’s traditional 4.4 kW emergency diesel alternator. The installation cost was around Rs. 19 lakh and the generation cost is Rs. 12 per kv per hour. The estimated savings for a lifespan of about 15 years is around Rs. 1 crore. The current diesel generator consumes a litre of diesel to produce five units of electricity. Captain Rajesh Bargoti, the commanding officer of the ship, said It took about six months to put the entire system in place. We are now using solar energy for lights and a couple of air conditioners.' The estimated profit generated in a ship service life of 25 years is Rs 2.7 crore in this small project alone. "Even if the system is used for 25 days in one year, the system can repay its cost in less than 10 years while protecting the nature," the Navy said.
